We felt it in Sitka. Long rumbling and shaking. No damage done except to the egos of the emergency planners.

It was a very interesting test of the emergency broadcast system. The sirens went off. The reverse 911 worked. Lots of people heeded the warnings and got in their cars to go to higher ground.

Two small problems. There is basically a single main road that parallels the shore. It's two lanes wide. Hard to evacuate 3000 people on a little bitty two lane road. Then there was the little problem of ice. The idea is to go to higher ground - when the roads entering the higher grounds are iced up such that you need chains you have an oopsy situation. Fortunately, we were prepared to handle the six inch high wave.

Here's the link to a video documentary that was done after the huge killer tsunami. It explains not just how it happened, but interviews a few of the people who survived it all. Compelling stuff, IMO,worth an hour of time. It's broken up into 6 or 7 ten minute videos...

Shouldn't be too hard to measure. The wavelength is long, and tide gauges are built so short wavelength stuff (sea waves) doesn't change them. They are basically long tube with the bottom down fairly deep. The wavelength of tsunami are in the km.

The thing I found odd was all the other measurements in this article are in metric, then a sudden switch to imperial units. That's odd.
